Oldenburg, 18-12-2003
Dear Sir, Dear
Madame,
The Energy and
Semiconductor Research Laboratory (EHF) at the Institute of Physics, University
of Oldenburg, Germany is hosting a workshop on the modelling of wind fields
within the boundary layer up to about 200m using MM5 at high horizontal and
vertical resolution. The workshop is taking place from the 23rd till
the 26th of February 2004 in Oldenburg, Germany.
This workshop is
ment for MM5 users in Europe that are focusing on wind field modelling for wind
energy usage and / or modelling at high resolutions. The structure of the
workshop is open, dynamic and interactive.
We have invited
Cindy Bruyere of the NCAR, Boulder, USA, who is a scientist working on MM5 at
NCAR. She will give several lectures /talks on using MM5 for the lower
planetary boundary layer region.
Test case
Throughout the
workshop we want to present the results on a small run. We would like you to
perform a run at your institute / university. In this way we want to gather as
many results as possible from as many different countries as possible.The idea
is that you make a run for three
PBL-schemes for 5 days for a certain stability class (stable, unstable,
or neutral situation), and use the results to plot three vertical profiles of
the average wind speed (including its errors) in comparison to a vertical wind
profile calculated from measured data. NCEP data of the last year are available
for 1*1° horizontal resolution, so this could be a good year to run the model
for. For this please inform us also if you have access to meteorological mast
data to validate the model with.
The admission fee of
the workshop is €100,-. For applying please send an email to: tim.de.paus@uni-oldenburg.de, please mention if you are willing to
participate in the test case. Please also mention if you are willing to give a
presentation on your MM5 research methods and/or results. Applications should
preferably be sent before the 23rd of January 2004.
If you would like to
see what we are doing, please check:

and:
More details on
finding a hotel and how to get to Oldenburg will be announced through this
website.
Hope to hear from
you soon!
Best regards,
Tim de Paus

Extra
At

configure.user) for each location for each attendant will be made.
Lectures
The
lectures by Cindy Bruyere of
NCAR will cover the following topics (preliminary information):
1)Introduction to PBL
2)Closure schemes
3)Similarity theories
4)MM5 and PBL
5)FDDA
Discussion groups
In addition to
discussing the themes of the lectures, the attendants will be able to discuss
some of the following topics (should there be a topic you miss in this list,
please inform us so we can take this into account):
TERRAIN domain size / nesting
What are the domain
sizes based on? How is the domain size influencing the results?
Initialisation
What are the general
features of different type of analysis data (es. what are the main differences
between between a FNL NCEP analysis and ECMWF)?
Skin (or surface)
temperature seems to be a critical parameter for many analysis (see reanalysis,
ECMWF). Which features present skin/surface temperature of analysis currently available and what are
the implication for MM5 model? How accurate is the sea surface temperature?
Configuration of the run
Which configuration
(input data, data assimulation) is the best for a real time simulation
(forecast) and which is best suitable for long term simulation of a past
situation?
Data assimilation
What is the exact
difference in functionality of the different kind of data assimilation availabe
for MM5 (e.g which are difference
between 4DDA, 3DVAR?)
Does surface data
assimilation add sensibly accuracy to the simulation?
Does observational
data assimilation coming from a 100 m mast add some information or flow in this
region is completely parameterized?
PBL modelling up to 200 m
What are the results
so far? (in addition to test case)
